FIG. 15 is a representation illustrating two diagrams representative from top to bottom of the power produced by the user of the device and of the power consumed by the device. - In
FIGS. 1 to 4 and 7 to 12, the different parts of a control device according to the invention can be seen designed to enable remote control of an electric equipment unit such as a medium-voltage electric cubicle or a power circuit breaker. - This device mainly comprises a
remote control 1 and adongle 2 designed to be fitted in removable manner in acontrol interface 3 of the equipment unit to be connected to the mechanism of the equipment unit by means of a connector (not shown). The equipment unit comprises a motor-driven operating mechanism, a local control unit comprising two buttons respectively for opening and closing, a switch designed to enable local or remote control of the equipment unit, and an indicator of the status of the equipment unit. - In
FIG. 1 , thisremote control 1 is in the closed position and presents a substantially rectangular shape. - This
remote control 1 is formed by acase 4 comprising twoparts buttons location 7 designed to receive thedongle 2. Thesecond part 4 b of thiscase 4 presents a substantially rectangular cross-section and comprises an opening having a shape matching the external shape of thefirst part 4 a so as to enable sliding of thefirst part 4 a inside thesecond part 4 b between an open position as illustrated inFIG. 3 and a closed position as illustrated inFIG. 1 , passing via the semi-open position illustrated inFIG. 2 . The open position enables thedongle 2 to be removed from itslocation 7 and allows access to the actuatingbuttons - This
dongle 2, once it has been removed from itslocation 7, is designed to be fitted in thecontrol interface 3 of the equipment unit (as illustrated inFIGS. 5 and 6 ) to be connected to the mechanism of the equipment unit by means of a connector (not shown). - According to the invention, this device comprises means 8 for preventing closing of the
case 4 of the remote control if thedongle 2 has not been previously replaced in itslocation 7 inside thecase 4. - These means comprise a
latch 8 cooperating with the housing of thesecond part 4 b of thecase 4, saidlatch 8 being movable between a first position in which it is retracted inside the first part ofcase 4 a by the fact that thedongle 2 is inserted in this first part ofcase 4 a, and a position in which thislatch 8 is salient from thefirst part 4 a of the case and comes into contact with a part of the housing of the second part ofcase 4 b when the dongle is extracted from this first part ofcase 4 a so as to prevent closing of the case. - For this purpose, the
latch 8 comprises a part in the form of abridge 10 designed to receive thedongle 2 with sliding, saiddongle 2 being able to slide between a part of thefirst part 4 a of the case and saidbridge 10 when this dongle is inserted in this first part of case or when the latter is extracted therefrom, the end part of said dongle presenting a square cross-section cooperating with the opening of the bridge. - This
bridge 10 is also fitted sliding inside thisfirst part 4 a of the case between a bottom position in which thelatching member 11 is salient from the first part ofcase 4 a and cooperates with the housing of the second part ofcase 4 b, the dongle not being inside the bridge, and a top position of the bridge in which thelatching member 11 is retracted and releases this housing enabling relative sliding of the two parts, the dongle being inserted inside the bridge. This change of position of the bridge is obtained when the dongle is inserted, the latter cooperating with aramp 12 belonging to thebridge 10, the latter being biased to the bottom position by aspring 13 pressing on the one hand on the housing of the first part ofcase 4 a and on the other hand on thebridge 10. - This remote control enables remote operation as it operates without any wiring with a short-range radio system (for example ZigBee) operating over a few tens of metres, which means that it is able to operate through a partition (wall, door, etc.). ZigBee is a high-level protocol enabling communication of small radios with low consumption. This protocol integrates data encryption ensuring security of information between transmitters and receivers.
- In order to prevent interference operation of a second equipment unit situated nearby and having a dongle inadvertently connected to its local control unit, there is unique pairing between the remote control and its dongle. At the time the remote control and its dongle are manufactured, final pairing is performed based on the MAC address of the ZigBee radio guaranteeing the impossibility of controlling two dongles from the same remote control unit.
- As the equipment units are only operated very seldom, on average once every five years, the remote control advantageously only uses the power provided by pressing on the actuating buttons to supply the radio transmitter situated in the remote control, whereas the radio receiver, situated in the equipment unit, benefits from the stored low-voltage power supply of the electric control.
- The remote control thus comprises two power generators respectively activated by pressing on two buttons.
- The principle described with the ZigBee technology can also apply to other wireless communication technologies (for example infrared technology, etc.).
- The sequencing principle will be described in the following with reference to
FIGS. 13 to 15 . - The electric circuitry designed to enable this sequencing comprises the following components: a
generator 14, arectifier bridge 15, aswitch 16, acontrol device 17, apower convertor 18, amicrocontroller 19 able to store a datagram D, atransceiver 20 and acapacitor 21. - In the course of
sequence 1 illustrated inFIG. 13 , pressing on one of the buttons orgenerators 14 stores energy E1 in thecapacitor 21 and a part E2 of this energy is used to store the datagram D to be transmitted. Reference should advantageously be made toFIG. 15 illustrating power production and consumption during these sequencings. - In the course of
sequence 2 illustrated inFIG. 14 , releasing the button or the generator again stores energy E3 in capacitor, sends the stored datagram tosequence 1, this action consuming energy E4, and sends an acknowledgement of, which consumes energy E5. - Energy is thus stored twice (when pressing and when releasing the generator) with transmission of a datagram only when the button is released.
- Operation of the control device according to the invention will be described in the following with reference to the figures.
- In
FIG. 1 , thecase 4 of theremote control 1 is closed and thedongle 2 is stowed inside theremote control 1. - When the user wants to use this remote control, he opens the
case 4 as illustrated inFIGS. 2 and 3 and removes thedongle 2 as illustrated inFIG. 4 in order to insert the latter in thecontrol interface 3 of the equipment unit, as illustrated inFIGS. 5 and 6 . - In this position of the case, it is then possible to actuate the opening or
closing buttons - When one or the other of these buttons is actuated, the device operates according to the sequencing described in the above.
- In this open position of the remote control, it is impossible to close the
case 4 of the remote control, for without the presence of thedongle 2, thebridge 10 is biased to the bottom position and the latchingmember 11 of thelatch 8 prevents relative sliding of the twoparts case 4, as illustrated inFIG. 7 . - After the
remote control 1 has been used, the user puts thedongle 2 back in itslocation 7 inside thecase 4, which leads to thebridge 10 being moved to a top position as illustrated inFIGS. 8 and 9 , resulting in the latchingmember 11 in a retracted position enabling relative sliding of the twoparts case 4 and therefore closing of thecase 4. - The
dongle 2 is thus stowed in the case of theremote control 1 at the end of handling and the housing cannot be closed if the dongle is not present in its housing, which prevents the operator from forgetting the dongle on the product and then spending time looking for it, for example in the case of use on a very extensive site (for example a petrol refinery). - The invention therefore enables remote control of an electric equipment unit such as a medium-voltage cubicle, a power circuit breaker, etc. to be performed without any wiring and without any batteries by means of a simple device, with clear identification of the cubicle to be operated by means of a dongle, making control errors of a neighbouring cubicle practically improbable. It is thus possible to remote-operate different types of equipment units of the same manufacturer while at the same time guaranteeing control of the right unit (and not another unit), in simple and inexpensive manner. By means of the invention, remote control is also assigned to a single person, which also constitutes an advantage guaranteeing safety of operation.
- It should also be noted that the connector used is advantageously standard. The electrician can thus, with one and the same remote control, operate medium-voltage or low-voltage equipment or any device such as controllers or protection relays which act on circuit breakers, or switches whether the latter be overhead or underground.
- It should also be noted that the transmission system will advantageously be a short-range radio transmission system, but the latter may under other circumstances be an infrared system.
- The invention is naturally in no way limited to the embodiments that have been described and illustrated which have been given for example purposes only.
- On the contrary, the invention extends to encompass all technical equivalents of the means described as well as combinations thereof if the latter are performed according to the spirit of the invention.
